Letters' Patent N 99,67 5, dated February 8, 1870.

EXTENSIBLE ADVERTISING-FRAME.

The Schedule referred to in these Letters Patent and making part of the same I, DANIEL G. HOWELL, of Danby, in the county of Tompkins, and State of New York, have invented ce1-tain Improvements in Advertising-Frames, of which the following is a specification.

Nature and Objects 0f the In ren tion.

M y invention relates to that form or style of advertising-frames or boards, in which movable and adjustable letter-signs are inserted, and consistsin providing a frame, which I have denominated a Perpetual Extension-AdVertiser, so constructed t-hat itmay b e indefinitely extended and enlarged, and suit-able to be placed in exposed situations, and containing devices by which the names ot` any article of merchandise ot' fered for sale, or the names of the proprietors or firm, can be inserted and changed at pleasure, by means of adjustable letter-block or type, on which are represented letters of the alphabet, or numerical characters.

Description of Accompanying Drawings.

Figure 1 is a front view of the advertising-frame;

Figure 2, an isometrioal perspectivemof one of' the 'il Figure 3, a similar view ofthe bottom piece; Figure 4, a View of one of the letter-holders; Figure 5, a View of one ofthe letter-blocks; and

Figure (i, an end View ofthe letter-holder.

a, b, c, c', and (I, are the pieces coinposing the sides of the frame, the form of which is shown in an enlarged View, at iig. 2, the dovetailed groove being made to fit `the dovetailed projection` uponeach end of the letterholding bar F, shown at fig. 4.

This letter-holding bar has the tongue t t on the upper edge, and the groove gon the underfedge, the projection f being uponvthe face side. i

The form ofthe letter-blocks is shown at iig. 5, the forin off-the fspaces s s being the same as the form ot' the letter-blocks. i

The side pieces (t, b, c, c', and d, are made ofdiferent lengths, one short piece, like c c', on each end ofa single line of letters, or a longer one, like l), covering each end of two of the letteriholding bars, or one on each side, the whole length ofthe frame. By having the side pieces short, one or two ofthe lines` ofletteis may be changed without disturbing the remainder. The blocks may be of any suitable materia-l.

The manner of operating the traine is as follows:

The tongue t t, on the lower edge ot' the letter-holding bar F, slides into the groove in the lower edge of the head piece A A. be slipped in, in the sume manner, the side pieces being slipped on asA fast as may be required to retain the letter-bars in place, and, lastl f, the bottonrpieceB,

having the tongue t t, is slipped on, and the frame is complete.

Claims. v

I claim, as my inventionl. An advertising-frame, so constructed that the side-pieces und letter-holding bars may be indefinitely extended or multiplied, substantially as described and shown.

2. The combination and arrangement ot the side pieces a, b, c, c', and d, letterbolding barsv F F, letterblocks and bottom piece B, substantially as and for.

the purposes set forth.
